The IR/Serial connector wiring specifications are listed in the following table.
LAN (RJ-45)
The LAN RJ-45 port provides 10/100 Mbps communication via Cat5/5e/6 network cable. The LAN port automatically
negotiates the connection speed (10 Mbps or 100 Mbps), and whether to use half duplex or full duplex mode. The LAN
port is best used for connecting to a network switch.
FIG. 19 provides the pinouts and signals for the LAN connector and cable.
